Cuisine & Edibility
Cobia
Firm, moist white flesh with a mild, buttery flavor; moderate fat and large, clean flakes. Extremely versatile — excellent grilled, smoked, raw as sashimi, or used in ceviche.
Common Goldfish
Not consumed — a classic ornamental aquarium and pond fish; its vivid color and hardy nature make it one of the world's most popular decorative species.
Species Overview
Cobia
The cobia is a powerful pelagic fish that often follows large rays, sharks, and turtles. Its flattened head and elongated body resemble a shark. Excellent table fare with firm, white flesh, it is increasingly farmed in aquaculture.
Common Goldfish
The goldfish was one of the first fish to be domesticated, with selective breeding in China dating back over 1,000 years. Despite common misconceptions, goldfish can live 10-15 years with proper care and require far more space than a small bowl.
